... General Operation of the Serial Interface There are two phases to a communication cycle with the AD9704/ AD9705/AD9706/AD9707. Phase 1 is the instruction cycle, which is the writing of an instruction byte into the AD9704/AD9705/ AD9706/AD9707, coincident with the first eight SCLK rising edges. The instruction byte provides the AD9704/AD9705/ ...

... SCLK—Serial Clock. The serial clock pin is used to synchronize data to and from the AD9704/AD9705/AD9706/AD9707and to run the internal state machines. The SCLK maximum frequency is 20 MHz. All data input to the AD9704/AD9705/AD9706/ AD9707 is registered on the rising edge of SCLK. All data is driven out of the AD9704/AD9705/AD9706/AD9707 falling edge of SCLK ...
